Ping's S line of irons (S56, S57, S58, S59) have enjoyed huge success on Tour in the hands of players like Bubba Watson, Billy Horschel, Hunter Mahan, and Louis Oosthuizen, among others. The latest iteration, the S55, was introduced on Tour this week at The Barclays and appears to be in Hunter Mahan's bag. According to reports, Mahan is hitting them a bit longer and higher than the previous S56 model (an iron that's been used to win over 30 Tour events by various players).
The new S55 features a multi material construction with a stainless steel clubhead and tungsten toe weights as well as a redesigned custom tuning port that removes mass from the center of the club. The result is a higher MOI and more forgiveness than the S56. Vertical stabilizing bars in the cavity help improve consistency and distance control on scoring shots while a thermoplastic elastomer material in the tuning port improves feel. Slightly stronger lofts in the mid- and short-irons improve overall distance.
Those interested can expect the S55 to be available in golf shops on November 1st. (Photo: Courtesy of Ping)
